MICHAEL HURLEY, OF ONEONTA, NEW YORK.

HUB-LINER.

Specification of Letters Patent.

Patented Au 28, 1917.

Application filed May 3, 1917. Serial No. 166,202.

To all whom it may concern Be it known that 1, MICHAEL HURLEY, a citizenof the United States, and resident of Oneonta, in the county of Otsegoand State of New York, have invented certain new and useful Improvementsin Hub- Liners, of which the following is a specification. V

The present invention has reference, gen erally to railway rolling stockand the invention relates more particularly to an im proved hub liner.

The invention has for its dominant object to provide a hub liner fordriving wheels of locomotives whereby lateral play of the drive wheelswill be eliminated, thus overcoming liability of derailment and otherdangers incident to such conditions.

Another obiect of the invention is to provide a hub liner so constructedas to allow the quick arranging of the same upon the drive Wheelreceiving axle or axles of the locomotive without the necessity of anextensive or special equipment of tools.

It is also an object of the invention to provide a hub liner capable ofadjustment in order that the same can be used upon hubs varying in size.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of various possibleembodi merits of my invention Figure 1 is a vertical section through theimproved hub liner applied bearing block of a locomotive truck,

Fig. 2 is a side elevation thereof partly I. in section;

Fig. 3 an end elevation of the same.

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

Certain features and aims of this invention will be more readilyunderstood if the following facts be borne in mind: The bearing blocksof locomotive trucks, after a short period of use are worn to such anextent by the locomotive drive wheels as to permit the development oflateral play or sway of the wheels thereby rendering the sameexceedingly dangerous if used thereafter, due to the liability ofderailment of the locomotive and the weakening of the axle by reason ofthe abnormal stress imparted thereto by the wabbling or swaying drivingwheels. The above are among the dominant aims of this invention, andare, among others, attained in the constructions of the nature of thathereinafter described.

Referring now more specifically to the drawings, the improved hub linermay be stated to comprise a plurality of sections designated 1 and 2having marginal flanges 3 and 4 formed upon certain of their sides,portions of the said flanges being extended laterally to provideapertured lugs 5 through which connecting bolts 6 are passed in orderthat the several sections may be securely united. Correspondingsemi-circular recesses 7 are formed within the adjacent portions of thesections 1 and 2 and are of a size to snugly engage the axle A of thelocomotive truck upon which driving wheels TV are mounted at either end.

Bearing blocks H are carried by the opposite sides of the locomotivetruck and are adapted to have arranged over their outer ends the flangedsections 1 and 2, it being understood that the said sections are fixedlyengaged therewith through the medium of the connecting bolt 6 passingthrough the apertured lugs 5. To look the bolts, suitable nuts areturned into engagement with the screw-threaded extremities thereof andare prevented from having undue movement by passing cotter pins or thelike through said screw-threaded extremities.

l/Vithin the flanged outer sides of the section 1 and 2 notches orrecesses 8 are formed and serve as means for permitting the pins whichhold the usual grease cups in the bearing H to be removed or replacedwithout interfering with the operation or positioning of the hub linerin any way.

From the foregoing, it will be understood by workers in the art thatwith my improved hub liner, the existence of play or lateral movementbetween the bearing blocks of locomotive trucks and the adjacent drivewheels will be eliminated and further, the hub liner, due to theprovision of the connecting bolts 6 may be readily arranged uponbearings varying in size. Further, it will be understood that the linermay be arranged upon a bearing and a locomotive truck respectivelywithout an extensive or special equipment of tools and will obviate thenecessity of Welding and fitting the same to the bearing either by handor by the use of the conventional oX-acetylene Welding process.

If it be desired the sections 1 and 2, can be formed of differentthicknesses dependent upon the play or space existing between the huband its adjacent driving Wheel.

Manifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claims Iconsider Within the spirit of my invention.

I claim:

1. A hub liner including a plurality of sections having correspondingrecesses formed in their adjacent portions, and means passing throughsaid sections for adjustably connecting and clamping the same to abearing block of a locomotive truck.

2. A hub liner including a plurality of sections having correspondingrecesses formed in their adjacent portions, apertured lugs formed uponthe outer corners of said sections and projecting laterally therefrom,and bolts passing through the apertured lugs for adjustably connectingand fastening the sections to a bearing block of a locomotive truck. 7

3. A hub liner including a plurality of sections having correspondingrecesses formed in their adjacent portions, flanges formed upon theouter sides of the sections having laterally extending apertured lugsprojecting therefrom, and bolts receivable through the apertured lugsfor adjustably connecting and clamping the sections to a bearing blockof a locomotive truck.

4:. A hub liner including a plurality of sections having correspondingrecesses formed in their adjacent portions, marginal flanges formed uponthe outer sides of said sections and having laterally extendingapertured lugs projecting therefrom at points, said flanges also havingrecesses also formed therein, and bolts receivable through the aperturedlugs for adj ustably receiving and clamping the sections to a bearingblock of a locomotive truck.

In testimony whereof, I aflix my signature hereto.

MICHAEL- YHURLEY.
